Haha nope, but his pictures described that part of things pretty well. It does look great. Regulated screws have always caught my eye and this is no exception.
It's just depending on the gun it seems fitting the ERH on an octagon can be as simple as milling the backside flat or can be as involved as mating to an angle on the octagon which I imagine is quite a bit harder. The custom smiths get $1k give or take for the octagon, and I'm curious what about the process justifies the cost.
I see that, milling the flat on the Ruger housing at the right distance from the face of the barrel flat to the center of the ejector hole in the frame gets into the narrow cross sectional contour of the housing and the housing ends up narrower than the barrel flat as shown. If one wanted the flat on the housing the same width as the barrel flat, one would have to make a new housing with a 'fatter' cross section.
The MK Technologies housing is a little beefier in cross section and it might work out.
its refreshing to see real gunsmithing on this forum as opposed to the "dremel tool" Jobs some folks pass off .The attention to detail , the quality of the work is outstanding , folks with some knowledge will recognize the fine details not only in the work , but in the set ups shown in the pictures , there are details there for those who pay attention . For example look at the arbor for the jewelers saw ; extra support to eliminate chattering ... the list goes on . Thank you sir for your time and sharing .
